[0078] A quartz substrate smooth surface ultrasonic quantitative cleaning process, comprising the following steps:
[0079] S1: Material selection: Before the quartz substrate is subjected to ultrasonic quantitative cleaning, the quartz material is selected first, and then the quartz substrate is detected after the selection is completed, and the quartz substrate to be cleaned is obtained after the detection is completed;
[0080] Among them, the quartz substrate that has been strictly screened and detected has more uniform and stable surface properties, which is conducive to the implementation of the ultrasonic cleaning process;
[0081] S2: Cleaning scheme design: the characteristics of the quartz substrate to be cleaned are analyzed, and the ultrasonic quantitative cleaning scheme is formulated according to the confirmed characteristics, and the standard cleaning scheme is obtained after the formulation is completed;
[0082] Among them, through comprehensive characteristic analysis and accurate cleaning strategy, the original physical and chemical properties of the quartz substrate can be ensured during the cleaning process;
[0083] S3: Cleaning equipment detection: the equipment involved in the standard cleaning scheme is confirmed, and each equipment is functionally detected, and the cleaning preparation of the quartz substrate is performed after the functional detection is qualified;
[0084] Among them, through comprehensive equipment function confirmation and detection, it is ensured that all the equipment is in good working condition, and the downtime caused by equipment failure is reduced;
[0085] S4: Cleaning implementation: according to the standard cleaning scheme, the quartz substrate to be cleaned is cleaned, and the cleaning process of the quartz substrate to be cleaned is recorded in real time, and the cleaning process data is obtained after real-time recording;
[0086] Wherein, by recording the changes in the cleaning process through the camera or direct observation, the dynamic of the cleaning process can be monitored in real time, and potential problems can be found and solved in time;
[0087] S5: Quartz substrate detection: the quartz substrate after ultrasonic quantitative cleaning is detected after cleaning, and the detection result is marked as quartz substrate detection data;
[0088] Wherein, through strict finished product detection, unqualified products can be found and handled in time during production;
[0089] S6: Detection data adjustment and evaluation: analyze the quartz substrate detection data, adjust the cleaning according to the analysis result, evaluate the analysis result, and finally transmit the cleaning adjustment data and evaluation data to the display terminal for display;
[0090] Wherein, according to the comparison difference, the cleaning scheme is redeveloped to ensure the maximization of cleaning effect, which can significantly improve the accuracy and efficiency of cleaning.
[0091] For S1, the quartz material is selected, and after selection, the quartz substrate is detected, including:
[0092] Selecting materials with SiO2 content higher than 99.5% as quartz materials for quartz substrates, and detecting the purchased quartz substrates after confirming the quartz materials;
[0093] The detection includes appearance inspection, purity detection, size detection, shape detection, surface roughness detection, optical performance detection and chemical stability detection;
[0094] Wherein, the appearance inspection is to check the defects on the surface of the quartz substrate, including cracks, bubbles and stains; the purity detection is to detect the SiO2 content and impurities by Fourier transform infrared spectroscopy; the size detection and shape detection are to detect whether the size and shape of the quartz substrate meet the preset specifications by using a microscope and a projector; the surface roughness detection is to detect the roughness of the surface of the quartz substrate using an atomic force microscope; the optical performance detection is to detect the transmittance and refractive index of the quartz substrate; the chemical stability detection is to detect the corrosion resistance and chemical stability of the quartz substrate;
[0095] After the appearance inspection, purity detection, size detection, shape detection, surface roughness detection, optical performance detection and chemical stability detection are all detected and qualified, each quartz substrate is uniquely coded, and the quartz substrate to be cleaned is obtained after unique coding.
[0096] Specifically, by strictly selecting quartz materials with SiO2 content higher than 99.5% as the substrate, the high purity and excellent physical and chemical properties of the quartz substrate are ensured. This provides a solid foundation for subsequent ultrasonic cleaning processes, helping to reduce impurity pollution and chemical reactions that may occur during the cleaning process. The detection process covers multiple aspects such as appearance, purity, size, shape, surface roughness, optical performance, and chemical stability, ensuring that the quartz substrate meets the use requirements in multiple dimensions. This comprehensive detection not only improves the quality of the quartz substrate, but also provides reliable data support for subsequent cleaning processes. High-precision instruments such as Fourier transform infrared spectroscopy, microscopes, projectors, and atomic force microscopes are used for detection, improving the accuracy and reliability of the detection. These technologies can accurately measure various parameters of the quartz substrate, providing scientific basis for the optimization of the cleaning process. Each quartz substrate is uniquely coded for easy tracking and management during subsequent production and quality control processes. This coding method helps improve production efficiency and ensures that each quartz substrate is properly processed and recorded. The quartz substrate that has undergone strict screening and detection has a more uniform and stable surface, which is beneficial to the implementation of the ultrasonic cleaning process. Ultrasonic cleaning can effectively remove dirt and impurities attached to the surface of the quartz substrate using high-frequency vibrations, and high purity and uniform surface properties can help improve cleaning effectiveness and efficiency.
[0097] For the characteristic analysis of the quartz substrate according to the quartz substrate to be cleaned in S2, the ultrasonic quantitative cleaning scheme is formulated according to the confirmed characteristics, including:
[0098] According to the detection results of the quartz substrate in the quartz substrate to be cleaned, the detection results are analyzed;
[0099] Before the characteristic analysis, the size of the silica oxide balls coated on the quartz substrate is confirmed;
[0100] The quartz substrate with silica oxide balls coated on the quartz substrate with a size of 1 μm-3 μm is marked as low-frequency analysis;
[0101] The quartz substrate with silica oxide balls coated on the quartz substrate with a size of 0.3 μm-1 μm is marked as mid-frequency analysis;
[0102] The low-frequency analysis and mid-frequency analysis of the quartz substrate include physical property analysis, chemical property analysis, and acoustic property analysis;
[0103] Among them, the physical property analysis is surface topography and adhesion; the chemical property analysis is contaminant type and cleaning agent selection; and the acoustic property analysis is sound wave propagation and cavitation effect.
[0104] Specifically, by analyzing quartz substrates based on the size of their silica beads, which are categorized into low-frequency and mid-frequency bands, more precise cleaning strategies can be developed for contaminants in different size ranges. This categorization helps better understand how contaminants interact with the substrate surface, thereby optimizing cleaning performance. Physical characterization (surface morphology and adhesion), chemical characterization (contaminant type and cleaning agent selection), and acoustic characterization (acoustic wave propagation and cavitation) provide comprehensive data support for the cleaning process. These analyses help identify the nature of the contaminants, select appropriate cleaning agents, and optimize ultrasonic cleaning parameters to ensure targeted and effective cleaning. Characterizing quartz substrates allows for more effective removal of surface contaminants while minimizing substrate damage. Precise cleaning strategies can avoid surface damage caused by over-cleaning and contaminant residue from under-cleaning. Comprehensive characterization and precise cleaning strategies ensure that quartz substrates maintain their original physical and chemical properties during the cleaning process, thereby improving product reliability and stability.
[0105] Formulate a plan for ultrasonic quantitative cleaning of quartz substrates analyzed in the low frequency band;
[0106] The ultrasonic quantitative cleaning scheme for quartz substrates analyzed in the low frequency band is as follows:
[0107] S2011: Preparation of experimental equipment, including 80KHz ultrasonic cleaning tank, Leica microscope, clean pure water system, power meter and timer;
[0108] S2012: Place the quartz substrate in an 80KHz ultrasonic cleaning tank, and the ultrasonic time is preset to 3 minutes, 6 minutes, 9 minutes and 12 minutes, for a total of four times;
[0109] S2013: setting the ultrasonic output power of the 80 kHz ultrasonic cleaning tank, wherein the initial ultrasonic output power is 100%, and the power is reduced by 10% each time the experiment is performed until the power is reduced to 10%, and each set of power settings is repeated at least 3 times;
[0110] S2014: Confirm the cleaning effect of the quartz substrate at different powers, and take the ultrasonic output power that achieves a final cleaning efficiency of more than 95% and no damage to the quartz substrate surface as the optimal power for the final ultrasonic cleaning solution;
[0111] S2015: performing actual ultrasonic quantitative cleaning on the quartz substrate to be cleaned according to the optimal power, and summarizing the cleaning data of the actual ultrasonic quantitative cleaning.
[0112] Specifically, by systematically setting different ultrasonic time and ultrasonic output power, the influence of these two key parameters on the cleaning effect can be comprehensively explored. This systematic experimental design helps to ensure the best cleaning conditions, clearly proposes that the cleaning efficiency needs to reach more than 95%, and requires that the quartz substrate surface be undamaged, which provides a clear quantitative standard for the evaluation of cleaning effect. This quantitative evaluation helps to ensure the consistency and reliability of cleaning quality, by confirming the cleaning effect at different powers and finding the best power that can ensure cleaning efficiency and avoid damage to the quartz substrate surface, which not only improves cleaning efficiency, but also prolongs the service life of the quartz substrate. The cleaning data of the actual ultrasonic cleaning are required to be summarized, which helps to continuously improve and optimize the cleaning process. Through data analysis, potential improvement points can be found to further improve cleaning quality and efficiency, which is not only suitable for low-frequency analysis of quartz substrates, but also can be adjusted as needed for other types of substrates and cleaning requirements, with strong universality and applicability, which can minimize unnecessary resource consumption while ensuring cleaning quality.
[0113] Developing an ultrasonic quantitative cleaning scheme for mid-frequency analysis quartz substrates;
[0114] The ultrasonic quantitative cleaning scheme for mid-frequency analysis quartz substrates is as follows:
[0115] S2021: Test equipment preparation, experimental equipment includes 400 kHz ultrasonic cleaning tank, ultrasonic cleaning generator, timer, solution container, pipette, magnetic stirrer and atomic force microscope;
[0116] S2022: Place the quartz substrate into the 400 kHz ultrasonic cleaning tank, the ultrasonic time is 3 minutes, and the ultrasonic power is full power;
[0117] S2023: Prepare the solution, which includes hydrogen peroxide, ammonia and pure water, wherein the hydrogen peroxide is 30%-35% hydrogen peroxide solution; the ammonia is 25%-28% ammonia solution; the pure water is high-purity deionized water or distilled water;
[0118] S2024: Add pure water to the 400 kHz ultrasonic cleaning tank, then gradually add hydrogen peroxide, and then gradually add ammonia, and record the amount of solution added each time;
[0119] S2025: After adding ammonia each time, run ultrasonic cleaning for 3 minutes, and then use the atomic force microscope to evaluate the cleaning efficiency, and the solution ratio that achieves a final cleaning effect of more than 95% is taken as the best ratio;
[0120] S2026: According to the best matching, the quartz substrate to be cleaned is actually ultrasonic quantitative cleaning, and the cleaning data of the actual ultrasonic quantitative cleaning is data summarized.
[0121] Specifically, a 400 kHz ultrasonic cleaning tank is used. The cavitation effect of ultrasonic waves of this frequency in the cleaning solution is strong, which can effectively separate the dirt from the surface of the quartz substrate and improve the cleaning efficiency. The cleaning time is set to 3 minutes to ensure the efficiency of the cleaning process, while avoiding the damage to the substrate caused by long-time ultrasonic cleaning. A magnetic stirrer is used to ensure uniform mixing of the cleaning solution, which improves the consistency of the cleaning effect. A pipette and a timer are used to accurately control the ratio of the cleaning solution and the cleaning time, making the cleaning process more controllable. By gradually adding hydrogen peroxide and ammonia, and recording the amount of each addition, the best solution ratio can be systematically explored. After adding ammonia each time, ultrasonic cleaning and cleaning efficiency evaluation are performed to ensure that the final solution ratio found is the best one, which can maximize the cleaning effect. Atomic force microscopy is used to evaluate the cleaning efficiency, which is a high-precision measurement method that can accurately reflect the surface changes before and after cleaning, thereby ensuring the accuracy of the cleaning quality. Each step has clear operation guidelines and recording requirements, making the cleaning process highly reproducible.
[0122] The ultrasonic quantitative cleaning scheme of the quartz substrate analyzed in the medium frequency band and the ultrasonic quantitative cleaning scheme of the quartz substrate analyzed in the low frequency band are fused to develop a cleaning scheme;
[0123] The fusion cleaning scheme is as follows:
[0124] S2031: Prepare 80KHz and 400 kHz ultrasonic cleaning tanks, Leica microscope, atomic force microscope, clean water system, power meter, timer, solution container, pipette, magnetic stirrer;
[0125] S2032: First, place the quartz substrate in the 80KHz ultrasonic cleaning tank for preliminary cleaning. The ultrasonic time is preset to 3 minutes, and the power is set to 100%. After preliminary cleaning, rinse the quartz substrate with pure water.
[0126] S2033: Place the quartz substrate in the 400 kHz ultrasonic cleaning tank for fine cleaning. The ultrasonic time is preset to 3 minutes, the power is set to full power, and the solution prepared according to S2023 is added to the 400 kHz ultrasonic cleaning tank.
[0127] S2034: Use the atomic force microscope to evaluate the cleaning efficiency of the quartz substrate cleaned in S2033. When the cleaning efficiency reaches 95% or more, the final ultrasonic quantitative cleaning scheme of the quartz substrate is developed. The standard cleaning scheme is obtained after the development is completed.
[0128] Specifically, the ultrasonic cleaning tank combined with 80KHz and 400kHz two different frequencies realizes the organic combination of preliminary cleaning and fine cleaning. The 80KHz ultrasonic cleaning can effectively remove most of the dirt and impurities on the surface of the quartz substrate, while the 400kHz ultrasonic cleaning can more deeply clean the small gaps and hard-to-reach areas, improving the overall cleaning efficiency. Through atomic force microscope evaluation, the cleanliness of the cleaned quartz substrate surface can be accurately measured to ensure that the cleaning efficiency reaches more than 95%. This high-precision evaluation method can ensure the consistency and reliability of the cleaning quality, meet the requirements of high-precision processes, and the ultrasonic time, power and other parameters in the cleaning scheme can be preset and adjusted, so that the cleaning process has high controllability. At the same time, using power meter and timer and other tools can accurately monitor and control the parameter changes in the cleaning process to ensure the stability and consistency of the cleaning effect, which can be adjusted and optimized according to different quartz substrate materials, pollution levels and cleaning requirements. For example, by changing the cleaning solution ratio, cleaning time and power and other parameters to adapt to different cleaning needs, in low frequency analysis, by changing the ultrasonic time and power for multiple experiments to find the best cleaning power, this method ensures the stability and reliability of the cleaning effect, in the middle frequency analysis, through the fine solution ratio and the way of gradually adding, the composition of the cleaning solution is optimized, the cleaning efficiency is improved, and the cleaning scheme combines the advantages of low frequency and middle frequency, first preliminary cleaning to remove most of the dirt, and then fine cleaning to deeply remove the residues in the small gaps, so as to realize high-efficiency cleaning effect.

[0151] Finally, the cleaning efficiency evaluation data, attribute corresponding and adjustment data are transmitted to the display terminal in the form of a chart for display.
[0152] Specifically, by comparing the detection data before ultrasonic quantitative cleaning with the original detection data of the quartz substrate, the area and degree of cleaning required can be accurately identified, thereby avoiding unnecessary cleaning steps and waste of resources. The cleaning efficiency evaluation is divided into three levels: meeting the requirements, basically meeting the requirements and not meeting the requirements. This clear classification helps to quickly identify the cleaning effect and ensure efficient execution of the cleaning process. According to the cleaning efficiency evaluation results, the cleaning scheme can be adjusted accordingly. For properties that do not meet the cleaning requirements, the specific problems can be further identified, and the cleaning scheme can be redeveloped based on the comparison difference to ensure maximum cleaning effect. This dynamic adjustment of the cleaning scheme can significantly improve the accuracy and efficiency of cleaning, while reducing substrate damage caused by improper cleaning. Finally, the cleaning efficiency evaluation data, attribute correspondence and adjusted data are transmitted to the display terminal in the form of a chart for display. This data visualization makes the cleaning process more intuitive and transparent.
